Abstract: A multifunction adapter for use in a motion sensor module holds a lens at the front of the adapter in a predetermined position and distance relative to a sensor mounted on a circuit board, and uses positioning projections at the rear of the adapter to set a predetermined distance of the adapter from the sensor and the circuit board. The adapter can be adjusted to set the focal point of the lens at an optimized position for the sensor. Additionally, a cover that shrouds the sensor is present on the rear side of the adapter for reducing or eliminating air flowing across and around the sensor. When the sensor is a passive infrared device, the reduction in air flowing around and across the sensor reduces the number of false signals.

Abstract: A wiring unit for an electrical connector having a housing with a first side and an opposing second side, an attaching portion on the second side and a latching portion adjacent the attaching portion. The latching portion couples the wiring unit to a standard support. Electrical wiring terminals are coupled to the housing and can receive electrical wires. A stuffer cap is selectively coupled to the terminals and the attaching portion. When the stuffer cap is coupled to the attachment portion, attachment of the electrical wires to the terminals using an impact tool can be accomplished without damaging the latching portion since the stuffer cap spaces the latching portion from the support surface when the wires are forced into the terminals. When the stuffer cap is coupled to the terminals, the stuffer cap eliminates or substantially reduces oxidation or corrosion on the terminals and wires.

Abstract: A communications station for use in a distributed audio system having two Hall-effect integrated circuits mounted on a printed circuit hook switch board, the hook switch board mounted within a handset cradle of the communications station. The Hall-effect integrated circuits place the communications station on-hook or off-hook, depending on the amount of ambient magnetic flux. The ambient magnetic flux varies with the presence or absence of a handset in the cradle. Thus, if a handset containing a magnet is in the cradle, and the applied magnetic flux is greater than the predetermined flux necessary to affect the Hall-effect integrated circuit, the communications station will go on-hook. When the handset and the resultant flux is removed from the cradle, the Hall-effect integrated circuit will change state and the communications station will go off-hook.

Abstract: The anti-flashover ring of the present invention includes a substantially cylindrical body having an outer surface with a plurality of passageways thereon. Each of the passageways pass from one of the sidewalls through the body to the other of the sidewalls of the ring. The passageways function to provide fluid communication between the atmosphere surrounding an accessory product such as a bushing insert and the interior of a connector mounted thereon when the connector is being pulled off the bushing insert. The fluid communication prevents a vacuum from forming between the connector and the bushing insert that can lead to a flashover between an electrical probe in the connector and a ground shield of the bushing insert. The anti-flashover ring is also configured to provide an indication to the operator installing the connector of when the connector is fully installed on the bushing insert.
